BCI Applications to Creativity: Review and Future Directions, from little-c to C<sup>2</sup>
No full textBCI devices are increasingly being used to create interactive interfaces between users and their own psychophysiological signals. Over the years, these systems have seen strong development as they can enable people with limited mobility to make certain decisions to alter their environment. Additionally, their portability and ease of use have allowed a field of research to flourish for the study of cognitive and emotional processes in natural settings. The study of creativity, especially little creativity (little-c), is one example, although the results of this cutting-edge research are often poorly systematized. The purpose of the present paper, therefore, was to conduct a scoping review to describe and systematize the various studies that have been conducted on the application potential of BCI to the field of creativity. Twenty-two papers were selected that collect information on different aspects of creativity, including clinical applications; art experience in settings with high ecological validity; BCI for creative content creation, and participants’ engagement. Critical issues and potentialities of this promising area of study are also presented. Implications for future developments towards multi-brain creativity settings and C2 are discussed

La rappresentazione della storia. Sempronio Asellione e Cicerone
No full textAttraverso l'analisi di due frammenti di Sempronio Asellione e di
alcuni luoghi ciceroniani si dimostra come tra il II e il I sec. a. C.
si affacci a Roma una nuova concezione della storiografia: essa dovrà
rispondere a nuove e diverse esigenze, dettate anche dalla crisi che
la Repubblica attraversa nel periodo considerato. Asellione si fa
promotore di una storiografia più attenta, in senso polibiano,
all'educazione dell'uomo politico, mentre la concezione dell'oratore
si ispira al modello della storiografia isocratea, tesa piuttosto
principalmente al diletto del pubblic

La neurodivergenza come presupposto della creatività : Dai processi immaginativi alla comprensione della realtà
No full textEffect of Stokes number and particle-to-fluid density ratio on turbulence modification in channel flows
No full textTwo-way momentum-coupled direct numerical simulations of a particle-laden turbulent channel flow are addressed to investigate the effect of the particle Stokes number and of the particle-to-fluid density ratio on the turbulence modification. The exact regularised point-particle method is used to model the interphase momentum exchange in presence of solid boundaries, allowing the exploration of an extensive region of the parameter space. Results show that the particles increase the friction drag in the parameter space region considered, namely the Stokes number, and the particle-to-fluid density ratio at a fixed mass loading. It is noteworthy that the highest drag occurs for small Stokes number particles. A measurable drag increase occurs for all particle-to-fluid density ratios, the effect being reduced significantly only at the highest value of. The modified stress budget and turbulent kinetic energy equation provide the rationale behind the observed behaviour. The particles' extra stress causes an additional momentum flux towards the wall that modifies the structure of the buffer and of the viscous sublayer where the streamwise and wall-normal velocity fluctuations are increased. Indeed, in the viscous sublayer, additional turbulent kinetic energy is produced by the particles' back-reaction, resulting in a strong augmentation of the spatial energy flux towards the wall where the energy is ultimately dissipated. This behaviour explains the increase of friction drag in particle-laden wall-bounded flows
Automatic CFD analysis of planing hulls by means of a new web-based application: Usage, experimental data comparison and opportunities
No full textComputational fluid dynamics (CFD) modelling is a powerful tool to analyze complex hydrodynamics problems like flow around bluff bodies and their interactions including flow separation and reattachments where analytical formulas are not applicable nor reliable. Nevertheless, a relevant limitation on the systematic adoption of automated CFD workflows for a given typology of problems is still present. In this work, the results of an automatic and web-based application, named LincoSim, specifically designed to perform automatic CFD modelling of planing hulls are presented. The tool uses only open-source software and deploys High Performances Computing infrastructures to take advantage of well-established yet innovative technological bricks. A detailed comparison for planing hull hydrodynamics analyses is performed in an “automated fashion” on a systematic series of four planing hulls previously studied experimentally over a wide range of Froude numbers. The numerical outcomes and the systematic series trends of total resistance, sinkage, dynamic trim, and wetted surface area are compared with the measured experimental results. This paper shows that today CFD automated workflows can be used to study planing hull hydrodynamics highlighting the fact that several innovative aspects involved in LincoSim could have a strong impact on the way CFD tools are adopted in modern marine industrial design
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
